Especially when, as Todd points out, your other options besides sit and hope are really pretty crappy. 

I have done some research and I have heard there is2 options, a assignment of a option contract or transactional funding.

Of course they can get a higher sale price if they are willing to take on someone who cannot get a loan, or are offering better terms than current loan options.

The options are very limited.

I ran into a small company that had gone to a guru event back in early 2000s and were sold on the sub too then lease option sand sandwich type deal and did not care about equity just about cash flow. 

Ideally, you'd want to be no more than 75% LTV, and 70% is better.If you don't want a DSCR loan, your next best option will be to partner with someone with good credit and enough income to qual.

@Adam Walker what are your options if they default?

It doesn't matter what your niche is the Chattanooga market has several options to explore.

Another option - Preferred Returns.

I don’t see an option for that here.
